FIX THIS:The process requiring absorption of energy is:
Correct answer: D. H→H
- A. F→ F
- B. Cl→ Cl
- C. O→ O
- D. H→H
Explanation
The amount of energy released when an electron is added to an atom is termed as electron affinity. Here for all the options other than D, the reaction is exothermic. The addition of a second electron to the O-ve ion requires more energy. The repulsion between the electron and the ion makes O-O2(negative) endothermic.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
